| Outline of Final Research Achievements |
Fluidized bed column adsorption system was investigated to develop separation process of tetramethylammonium hydroxide (TMAH). Effective adsorption of TMAH was achieved with activated carbon by closed circuit type of the fluidized bed column adsorption system. In addition, the adsorption rate of TMAH with activated carbon in the fluidized bed column adsorption system was successfully expressed by pseudo second order rate model, and the rate constant was consistent to that in the batchwise system.
